Nancy Drew lived in River Heights, USA, which some Drew scholars believe is in Iowa because Mildred Benson, the first of a long line of ghost writers to assume the pen name Carolyn Keene, pictured it so. Nancy Clue lives in River Depths, Illinois. And though Mabel Maney (if that is her real name!) is somewhat elusive about her past, she too hails from the mid-west—Appleton, Wisconsin, to be exact!
